Introduction for
The Automotive Board and The Communication Board

　　In the era of rapid technological advancement, PCB is a crucial part of electronic devices. The communication and automotive industries have strict demands on PCB performance and quality. Communication and automotive boards play irreplaceable roles with their unique features.

The Automotive Board
　　• Characteristics
　　It features vibration, high temperature and corrosion resistance for harsh automotive environments. Higher standards in materials and manufacturing are needed to guarantee circuit board stability and reliability.
　　• Application Field
　　Widely applied in automotive electronics like car audio, navigation systems, and electric vehicle charging stations, fulfilling functions such as vehicle control, infotainment, and safety monitoring.

The Communication Board
　　• Characteristics
　　Pursuing high speed, high frequency and other characteristics, with the characteristics of high-speed signal transmission and strong anti-interference ability, to ensure the stability and reliability of communication equipment.
　　• Application Field
　　Widely used in communication devices, network equipment and other fields, such as mobile phones, routers, base stations, etc., to meet the needs of information transmission and communication.

 The Difference
  　　Although communication board and automotive board both belong to the category of PCBs, they have significant differences in multiple aspects.
　　• Material
　　The Automotive Board employs materials with high temperature resistance and compressive strength, such as FR-4 TG170 material.
　　The Communication Board often uses high frequency and high-capacity materials, such as Rogers 4003C/Rogers 4350B/RT5880 and PTFE materials.
　　• Design
　　The Automotive Board requires consideration of characteristics such as anti - vibration and anti - high temperature, and it should be designed to be more stable and sturdy.
　　The Communication Board needs to consider high speed signal transmission and anti - interference capability, and more attention should be paid to signal integrity and anti - interference in design.
　　• Application Environment
　　The Automotive Board applied to automotive environments, it is necessary to be able to adapt to harsh working conditions such as high temperature, high humidity, vibration, etc.
　　The Communication Board applied in communication devices, it needs to meet requirements such as high-speed transmission and stability.
　　• Usage
　　The Automotive Board mainly used in automotive electronic products to meet functional requirements such as vehicle control and information entertainment.
　　The Communication Board Mainly used in communication devices to meet data transmission and communication needs.
